Application filed October 9,

3e it known that l. lt'iurrix GoLns'rnIN, eitizen ot the United States,residing at- Kevstoue, in the eouuhv ot' lvleDowell and State of WestVirginia, have invented certain new and useful lniproven'ients inStreet-tweepers, of which the following a speritieation.

This invention relates to streetsweepers, and has for its objeettoprovide a sweeper espeeially adapted to be propelled by an engine.although draft? animals may be emlo \'e l it desire. I

The sweeper eonsist-s ofa body sup 'iorted in part by traetion wheelsand having .a broom frame pivotally mounted upon the axle of the saidwhee-ls. Means. is provided tor swinging the frame, and av broom isjournaled in the frame. {in elevator is arranged within the body andisadapted to reeeive material from the broom, and an apron is hii'l gedlveonneet'edupon the body and is loeated under the lower forward portionoi the broom. A hail is connected with the trai'ue and the apron,whereby the free end portion oi the apron swings inunison with thel'ralue of the broom. A. trash reeeptaele is provided upon the body intowhieh the elev; tor is arranged to dump.

For a lull understanding ot the invention reterenee is to be had to thefollowing deseription and aeeomrnuiying drawings, in whieh-- I Figure lis a side elevation of the sweeper with one. of the. wheels removed; iis a side elevation. viewing the some from the opposite side to thatshown in Fig. 1; Fig. 3%

portion of the sweeper; and Fig". (E is a transverse sectional view ofthe rear portion of the sweeper. lfig. 5 is a detail plan view of aportion of the operating mechanism. i

vUorrespmuiing and like parts are referred to in the followingdescription and indieated in all the views of the accompanying drawingsby the same reference characters.

As illustratedin the aeeon'lpan ing drawings, t-he sweeper includes aplatform 1 which is Inount'ed a't itsirear portion upon pivoted frame 3.Wheels 4 are journaled to anisnn indieated at 5, may be Connected withSpecification of Letters Patent.

engine 6 is mounted upon the forward pore tion ot. the platform 1 and asprocket wheel is provided upon the engine shaftexte'rnallvef. the frameof the machine, which sproolol wheel is eonneeted by asproelret chain 6with a similar sproeket wheel on a shaft" which is mounted'in asuitable-bearing on the uin lerside ot the machine. A sprocket chain 13trained around tliel sproel'ietl' wheeltll on the same shaft with thesprocket upon the rear axle, so that-the nioti'onfllof.

the engine shatt will be transmittedto said axle; and the traet-lonwheels I which are] fixed upon the ends of theQa-XleQ -fA -'?tl hotly 8is mounted upon the platform 1 and also an operators seat 9.. An". ;-I.-

wardly and jt't'n'wardly inclined partition 10, is arranged in the body8 and a trough 11*.

is provided at. the lower rear end of; the

said partition. An apron is hinged attherear edgre of the trough 11 andhas its I I tree edge portion rearwardlv disposed. The

forward portion ofthe body 8 eonslitute's a trash reeeptaele and isprovided atits op? postte hltltH w1th doors 113 through which the trashmay be removed from the'szi'id" body. I

'trame l is pivotal mounted upon the" axle '3 and l,\ provided at oneside with an elongated bar 1;) \vhieh extends toward the 'toruardportion ot" the. platform 1 andfis within .l'tilt'lt ot' one oeeup vin nthesea-tt),

is iom'naled for rotation the v4 passes through arruate slots 17provided in;

the sides of the hodv 5%. it stub shaft 18 is earried at the forwardportion of one side of the frame 1 l and a gear wheel 19 is jonrnaledupon the said stuh shalt. The gear wheel lit meshes with a gear wheel 20llXOt'l tothe axle 2 at the end opposite the end -art-ringthe sproehet.wheel (3!. sproelt-et.

wheel ifl is fir-ted to the side ol' the gear wheel it) and a sproehetwheel 22 is fixed to one end portion oi the shaft of the broom 16 in thesame longitudinal plane as the sprocket wheel 21. A sprocket ehain 23passes around the sprocket wheel 31 and and its runs are at the oppositesides of the axle 9. it will thus be seen that the rov tation. of theaxle derived tl'n'eugh the sproeketz wheel 62 and the parts actuatingTilt the same is transmitted through the gear wheels and 19 to the shaft18, so that the said shaft will. rotate in a direction opposite to thedirection of rotation of the axle.

The rotation of said shaft 18 is transmitted.

extends down underthe free edge portion of the apron 12. Therefore itwill be seen that when the frame 14- is swung the broom 16 is raised orlowered within the body 8 and the free edge portion of the apron 12 isswung by the bail 24. in unison with the broom.

A shaft is journaled in the sides of the body 8 beyond the upper end ofthe partition 10 and a sprocket wheel 26 is fixed to one end of thesaid. shaft 25. A sprocket wheel 27 is fixed to one end portion of theaxle 2 and a sprocket chain 28 is trained around the sprocket wheels 26and 27 and is adapted to transmit rotary movement from the axle 2 to theshaft A sleeve 29 is mounted upon-theaxle 2 between the sides ofthe body8 andis located approximately concentrically with relation to the trough11. Endless belts 30 are trained around the sleeve 29 and the shaft 25and carry a series of buckets 31.

The operation of the sweeper is as fol lows: As it is moved over thesurface of a street, and the rear portion of the frame 14:

the trough 11. At the same time the buckets 31 move in an orbit aboutthe shaft 25 and the sleeve 29 and the upper run of the conveyer movesupward. Consequently the buckets scoop up the material from the trough11 and carry the same upward, and as the buckets turn over the shaft 25the material is dumped into the forward portion of the body 8. If at anytime it is desired that the broom 16 should cease its sweepingoperation, the forward end of the bar 15 is depressed, whereby the frame14 is swung upon the axle 2 and the lower portion of the broom 'lfi israised above the surface of the street. As the forward portion of theframe 14 descends, the gear wheel 19 will follow around the forwardportion of the gear wheel 20, but the teeth of the said gear wheels willremain in mesh.

Having thus described the invention, what is claimed as new is:

A. sweeper comprising a body, an axle supporting the same, ground wheelssupporting tl axle, a broom frame pivoted upon the axle, a. broomcarried by the broom frame and located in the body, means for rotatingthe axle, means operativcly connecting the axle with the broom, apartition located in the body and having its lower portion continuedinto a trough which is located below the axle, a conveyor mounted formovement along the partition, means for operating the conveyor from theaxle, and an apron extending from said trough beneath said brush.

In testimony whereof T affix my signature inpresence of two witnesses.
